Definitions
- the invention relates to a rollator-wheelchair combination.
- Rollators are commonly known and are used by people experiencing difficulties with walking, due to e.g. physical disabilities. Such devices enable a handicapped person to go for a walk on their own and allow them to travel from one place to the other. Usually, such rollators are provided with a small board to allow the handicapped person to sit on and rest for a while. When walking for a longer time period or a larger distance, the handicapped person may get tired and might want to rest for a long period or may want to be pushed in a wheel chair.
- rollator wheelchair combinations provide the possibility for the handicapped person to walk a while with the rollator wheelchair combination in its rollator position, and when getting e.g. too tired the rollator wheelchair combination can be changed in its wheelchair position. The person can then rest in the seat of the rollator wheelchair combination, while the companion pushes the rollator wheelchair combination, allowing them to travel further along together.
- rollator wheelchair combinations are usually permanently equipped with all the features of both the rollator and the wheelchair, such as footrests and a chair with a seat and a back support, which may make the rollator wheelchair combination relatively heavy.
- handles are needed that can accommodate a person leaning when used as a rollator, as well as a person pushing when used as a wheelchair.
- a person leaning on the device when used as a rollator assumes a position between the wheels of the rollator, whereas a person pushing the device when used as a wheelchair assumes a position behind the device.
- a rollator wheelchair combination is required to provide both positions, without impeding either functions of the rollator wheelchair combination.
- Publication EP1145696 discloses a rollator wheelchair comprising a removable seat plate.
- this object is achieved by providing a rollator wheelchair according to claim 1.
- a rollator wheelchair comprising a frame provided with at least two wheels, a first chair section mounted to the frame and a second chair section mounted to the frame, the first chair section comprising a back support and a first seat portion, and the second chair section comprising a second seat portion, wherein the first and second chair sections provide a seating arrangement, wherein the first chair section is detachable and wherein the second chair is arranged such that when the first chair section is detached a free walking space is present between the at least two wheels, allows conversion between two modes of operation.
- a first mode of operation as a rollator a person can stand between the at least two wheels and lean on the rollator wheelchair combination.
- a second mode of operation as a wheelchair a person can sit while another person pushes the rollator wheelchair combination.
- the hinge construction allowing the rollator wheelchair combination to fold and unfold, can be seen as an invention.
- two swivelling arms that are crosswise provided between two similar shaped profile sections, wherein the profile sections are provided with a hinge and a catching stop, wherein each swivelling arm at an end is connected with the hinge of one profile section and at an other end is connected with the catching stop of the other profile section, and wherein the swivelling arms are centrally connected to each other with a connection hinge, for folding the two profile section to each other and unfolding the profile section at a certain distance from each other.
- the rollator wheelchair combination can thus be easily and reliably folded and unfolded.
- the swivelling arms are approximately horizontally oriented when the rollator wheelchair combination is in a use mode, e.g. a rollator mode or a wheelchair mode.
- a footrest comprising an attachment element and an arm with a board
- the attachment element comprises two jaw members which are operable by a pressing mechanism to a spread position and which are movable towards each other by operation of the pressing mechanism into a release position
- the inner sides of the jaw members are adapted to the dimensions of profile sections of a frame of a rollator wheelchair combination
- each jaw member is provided with two recesses for receiving a pin.
- profiles of the frame of the rollator wheelchair combination can be seen as an invention.
- a profile section comprising at least one hollow portion extending along the longitudinal direction of the profile section, in which hollow portion at least one stop ridge is provided which is shaped to allow a nut to fit tightly in a mounting groove. Bolts and/or nuts can thus be easily attached to the profile section.
- a rollator wheelchair shown in fig. 1 , has a frame 1 provided with at set of front wheels 2, 3, a set of rear wheels 4, 5 and a set of handles 34, 35.
- a seating arrangement 6 is constructed by a first chair section 7 and a second chair section 8.
- the first chair section 7 has a back frame 10 carrying back support 11 that is hingingly connected to a seat frame 12 carrying a first seat portion 9.
- the second chair section 8 has a collapsible second seat portion 13.
- the back frame 10 is provided with two rollers 14, 15 that slide into guiding rails 16, 17 respectively mounted on a right side and a left side of the frame 1.
- the seat frame 12 is supported at the front 20 by the frame 1.
- the first chair section 7 is detachable from the frame 1 by sliding the rollers 14, 15 out of the rails 16, 17 and lifting it from the frame 1.
- the second chair section 8 is arranged such that, when the first chair section 7 is detached, as shown in fig. 2 , a free walking space 23 is cleared.
- the rollator wheelchair is in a first mode of operation as a rollator, wherein a person can stand between the rear wheels 4, 5, can lean on the handles 34, 35 and can find support from the rollator wheelchair combination.
- the frame 1 is constructed of two identical shaped profile sections 26, 27, as best seen in fig. 3 , and two swiveling arms 18, 19, as shown in fig. 2 .
- the profile sections 26, 27 are spaced apart from each other and placed symmetrically with respect to a centre plane 28, forming a left side profile section 27 and a right side profile section 26.
- Each profile section 26, 27 has three arms 31, 32, 33 that provide attachment points for respectively a handle 34, 35, a front wheel 2, 3 and a rear wheel 4, 5. Furthermore, arm 32 is here provided with a footrest 36. Swiveling arm 18 is connected to the right profile section 26 with a hinge 21 and falls in a catching stop 25 of the left profile section 27. Swiveling arm 19 is connected to the left profile section 27 with a hinge 22 and falls in a catching stop 24 of the right profile section 26. The swiveling arms 18, 19 cross in the centre plane 28 at intersection 29 where they are connected by a joining hinge 30. As shown in fig. 4 , the height at which the swiveling arms 18, 19 and the seat portion 13 are arranged leaves a free legroom 37 allowing a seated person enough space to dangle the legs freely without touching the ground.
- the profile sections 26, 27 are extruded from aluminum with hollow portions 38-40 extending along the longitudinal direction of the profile sections 26, 27, as shown in figs. 7 and 8 .
- Hollow portion 39 is provided with two stop ridges 41, 42 and shaped such that a nut 43 fits tightly in a thus formed mounting groove 44.
- the size of the mounting groove 44 is such that it accommodates an M8 nut of a nut and bolt combination.
- the profile sections 26, 27 can be pushed towards each other, as shown in figs. 5, 6 , forcing the collapsible second seat portion 13 to collapse.
- the swivelling arms 18, 19 extend almost parallel along the centre plane 28. In this collapsed position the rollator wheelchair takes up less space allowing easy storage.
- the rollator wheelchair is provided with footrests 36.
- the attachment thereof is an invention in its' own right, figs. 9 , 10 .
- a footrest 36 comprising an attachment element 45 and an arm 46 provided with a board 47; wherein the attachment element 45 comprises two jaw members 46, 47 which are pressed by a pressing-mechanism 50 in a spread position and which are movable towards each other by operation of the pressing-mechanism 50 into a release-position, and wherein each jaw member 48, 49 is provided with at least one recess 51, 52 for receiving a pin 53, 54.
- the inner sides of the jaw members 48, 49 are adapted to accommodate profile sections 26, 27.
- each of the jaw members 48, 49 is further provided with a second recess 52 for receiving the pin 53, 54.
- the profile sections 26, 27 are pierced by pins 53, 54. Attachment of the footrest 36 is achieved by pushing the pressing-mechanism 50, placing recesses 51, 52 of jaw member 48 around pin 53, rotating the arm 46 of the footrest 36 in the direction of arrow 55 , fig. 10 , till recesses 51, 52 of lower jaw member 49 are positioned behind pin 54 and releasing the pressing-mechanism 50. In this manner, the footrest 36 is attached and secured simple and direct.
- a further invention aimed at full conversion between a condition for performing a rollator function and a condition for performing a wheelchair function is the embodiment of the handles 34, 35.
- the handles 34, 35 in fig. 16 are in a position for the wheelchair function and can be rotated to a position for the rollator, as shown in fig. 14 and 15 .
- handle 34 is shown in close-up.
- the handle 34 is mounted in handle holder 57 of arm 31 of the profile section 26.
- the clamp ring 56 is positioned such that in the rollator position the handle 34 is at a comfortable height for a person using the rollator, as can be seen in figs. 11 and 12 .
- the clamp ring 56 allows memorizing the preferred height of the handle 34 for the rollator function when the handle 34 is actually in the position for wheelchair function.
- the clamp ring 56 is shown in fig. 13 in more detail with an opening 59 for receiving the handle 34, 35 and a recess 60 for receiving a nut of a nut and bolt combination. With the nut and bolt combination the clamp ring 56 is clamped to the handle 34, 35.
